In American and British English, a word family often changes its stress as it grows: PHO-to-graph, pho-TOG-ra-pher, pho-to-GRAPH-ic. Each new suffix pulls the weight to a new syllable and squeezes the other vowels down to a weak "uh". Listeners from those varieties rely on that moving weight to tell the members of the family apart.
